ZEISS Ultralight 1913 MS Rings 30mm Low – 21.6mm Height
The ZEISS Ultralight 1913 Mil-Spec Rings in 30mm/Low offer a centre height of 21.6mm (0.85″) and are machined from aircraft-grade 7075-T6 aluminium with a Mil-Spec Type III, 30-micron hard-anodised matte black finish. An integral anti-cant bubble level sits in the top half of each ring, visible from the shooting position without disrupting your stance — a genuine advantage for precision and long-range work. An integral bottom recoil lug locks the mounting point and preserves zero under heavy recoil. The interface is MIL-STD-1913 Picatinny, so the rings fit any standard Picatinny-railed rifle. Fasteners are Type 303 stainless steel top cap screws with black oxide finish, and all machined leading edges are micro-radiused for a non-marring design. The rings are supplied as a pair in a hard case.

These rings fit perfectly on my rifle and stay stable even during heavy firing. The bubble level is visible and helps with alignment. The matte finish looks professional and the build feels solid.

I’ve used these rings for several months in different conditions. They maintain zero after repeated firing and the recoil lug keeps them secure. No wobble or movement during use.

The height is ideal for long-range shooting. The anti-cant level is useful for quick alignment. Slight concern about the finish durability in harsh environments, but overall very reliable.

Excellent quality and precision. The micro-radiused edges prevent scratching the rail. Easy to install and holds firm under recoil. Would recommend to anyone needing stable, accurate mounting.
